You should ask the one(s) who have ported Jump'n'Bump, because SMW is basically a fork of J'n'B.
I doubt the devs of SMW would do it, because they're trying to keep a pretty low profile (in fear of Nintendo's wrath) until SMW is absolutely perfect. They won't even add network multiplayer support until then.

super mario war is this fun game where you can use many characters from different game series and get power ups and stomp on each other. Just type in Super mario war into google and it should be the first website. get the one for PC or Mac (whichever one you are using). the newest version is 1.8
